* Clean up compiler warnings in nxcompFernando Carvajal2016-04-275-61/+129
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit removes several warnings in nxcomp related to unused but set variables. It also replaces tempnam function with the more secure one mkstemp and there has been removed another warning related to setgid and setuid returning values not being checked. So these were the compiler warnings in nxcomp that have been fixed: Loop.cpp: In function ‘int ParseRemoteOptions(char*)’: Loop.cpp:9423:7: warning: variable ‘hasLimit’ set but not used [-Wunused-but-set-variable] int hasLimit = 0; ^ Loop.cpp:9424:7: warning: variable ‘hasRender’ set but not used [-Wunused-but-set-variable] int hasRender = 0; ^ Loop.cpp:9425:7: warning: variable ‘hasTaint’ set but not used [-Wunused-but-set-variable] int hasTaint = 0; ^ Loop.cpp:9427:7: warning: variable ‘hasStrict’ set but not used [-Wunused-but-set-variable] int hasStrict = 0; ^ Loop.cpp:9428:7: warning: variable ‘hasShseg’ set but not used [-Wunused-but-set-variable] int hasShseg = 0; ^ ServerChannel.cpp: In member function ‘virtual int ServerChannel::handleWrite(const unsigned char*, unsigned int)’: ServerChannel.cpp:2132:9: warning: variable ‘hit’ set but not used [-Wunused-but-set-variable] int hit; ^ Proxy.o: In function `Proxy::handleSaveAllStores(char const*) const': Proxy.cpp:(.text+0x2cac): warning: the use of `tempnam' is dangerous, better use `mkstemp' Pipe.cpp: In function ‘FILE* Popen(char* const*, const char*)’: Pipe.cpp:240:23: warning: ignoring return value of ‘int setgid(__gid_t)’, declared with attribute warn_unused_result [-Wunused-result] setgid(getgid()); ^ Pipe.cpp:241:23: warning: ignoring return value of ‘int setuid(__uid_t)’, declared with attribute warn_unused_result [-Wunused-result] setuid(getuid()); ^ There was also a hidden problem in the way Proxy::handleSaveAllStores was checking for an error in the returning value from the call to the virtual method handleSaveAllStores of the specific proxy class really being used (ClientProxy or ServerProxy). Former code was considering the value 0 as the returning value in case of an error whereas both subclasses return the value -1 when there is an error in their handleSaveAllStores method. This bug has been fixed in this commit taking advantage of the modification that was already being made to this method in order to replace tempnam function with the more secure one mkstemp.

* Remove TextCompressor class and files from nxcompFernando Carvajal2016-04-157-143/+0
| | | | | | | | | | | | This commit removes TextCompressor class references from ClientCache and ServerCache as it's no longer used after removing old protocol's compatibility code from nxcomp. It also removes the attribute textCache from both classes as it's no longer used either. Finally the header and source files associated with the TextCompressor class are also deleted and removed from the compilation process. Refs: ArcticaProject/nx-libs#108
* Remove obsolete compatibility files from nxcompFernando Carvajal2016-04-1225-3960/+1
| | | | | | | | This commit removes obsolete compatibility files whose components were only used to handle compatibility with old protocol versions that are no longer supported. Refs: ArcticaProject/nx-libs#108
* Remove compatibility code for nxcomp before 3.5.0Fernando Carvajal2016-04-1258-2492/+649
| | | | | | | | | | | | | | As a part of nxcomp's clean-up process, compatibility with old protocol versions has been set now at 3.5.0. This commit removes compatibility code from nxcomp so the minimum supported version changes from 1.5.0 (protocol step 6) to 3.5.0 (protocol step 10). At this moment the removal is not complete and it will be followed by some other commits, in order to get rid of several components and files that are no longer used as they were only needed to work with old protocol versions.

* Provide support for re-enabling Xinerama on session resumptions.Mike Gabriel2015-12-301-0/+1
| | | | | | | | | | | | | | By design, when resuming a session, Xinerama can only be re-enabled by NX option parsing. Thus, this change introduces a "xinerama" NX option that can be loaded via an options file into NX agent when resuming a session. The new xinerame NX session option also allows switching on Xinerama at session startup via an option file. When implementing the new NX Xinerama support into clients (like TheQVD, X2Go Client, etc., this new xinerama NX option should be used for activating Xinerama in the NX / QVD / X2Go session.

This involves creating a new API call void NXTransCleanupForReconnect(void); which basically cleans up the global state for the connection but does not exit the process. Background ========== This is needed for the IOS platform, where the nxproxy model of forking does not work. Also NX handles most of the errors with an "exit" call which in IOS cannot be easily handled.

| | | | | | | | | | | | | | | | | (605_nxcomp_Types.h-dont-use-STL-internals-on-libc++.full+lite.patch). The nx-libs-lite package does not compile on OS X Mavericks because Apple's clang compilers now default to compiling against the libc++ STL rather than (their outdated copy of) libstdc++. While the compiler still allows changing that, we should not rely on this being possible forever. The compiler chokes in Types.h, specifically the clear() methods in subclasses of vectors that use implementation details of the GNU STL. The attached patch fixes these compilation issues by not overriding the clear() method when compiling against libc++, since the libc++ headers seem to do essentially the same as the overriden method.

The Fedora review of NX (redistributed) caught the following rpmlint issue: This executable is calling setuid and setgid without setgroups or initgroups. There is a high probability this mean it didn't relinquish all groups, and this would be a potential security issue to be fixed. Seek POS36-C on the web for details about the problem. Ref POS36-C: https://www.securecoding.cert.org/confluence/display/seccode/POS36-C.+Observe+correct+revocation+order+while+relinquishing+privileges This patch adds initgroups() calls to the code to initialize the supplemental group list.

| | | | | | | | | | | The Mac OS X 10.5 SDK requires the second argument of FD_ISSET to be writeable, although it does only access the data. Given that we have a const pointer for a const struct, copy and pass that. . Note that this is merely a workaround for OS X 10.5, as 10.6 and later define the second argument of FD_ISSET as const struct const *foo, too. . It is safe, as data is accessed read-only by FD_ISSET, even on 10.5.

* Fix building against libpng 1.5 (006_nxcomp_libpng15.full+lite.patch).Mike Gabriel2015-02-091-3/+3
| | | | | | | | | | | | | | | From the libpng homepage... The libpng 1.5.x series continues the evolution of the libpng API, finally hiding the contents of the venerable and hoary png_struct and png_info data structures inside private (i.e., non-installed) header files. Instead of direct struct-access, applications should be using the various png_get_xxx() and png_set_xxx() accessor functions, which have existed for almost as long as libpng itself. (Apps that compiled against libpng 1.4 without warnings about deprecated features should happily compile against 1.5, too. Patch origin: Fedora packagers of libXcomp3.
